  • Cellulose food casing, cellulose composition and production method therefor
    Patent number: 6547999
    Abstract: The present invention provides a method of preparing a cellulose solution suitable for extrusion as a seamless tubular film by providing a pulp of substantially open-ended fibrillated softwood fibers having a mean fiber length less than 2.0 mm and then dissolving the pulp in a suitable solvent to produce the cellulose solution. In addition, the present invention provides a method of preparing a cellulose food casing from a cellulose solution of the present invention.

  • Long life battery separator
    Patent number: 5700600
    Abstract: A battery separator of a noncellulosic nonwoven substrate extrusion coated on at least one surface with a cellulose film and process for making such separator by contacting a nonwoven noncellulosic textile substrate with a cellulose or cellulose derivative solution on at least one side of said substrate; converting the solution to a solid cellulose or cellulose derivative, preferably having a degree of polymerization of at least 350, more preferably at least 600, to form a coated substrate; washing and drying the coated substrate to provide a battery separator, preferably having a absorption rate of at least 6 mm/5 min. and a 30% KOH absorption of at least 200 g/m.sup.2.
